What other types of free speech activity are constitutionally protected?
The First Amendment covers all forms of communication including music, theater, film, and dance. The Constitution also protects actions that symbolically express a viewpoint. Examples of these symbolic forms of speech include wearing masks and costumes or holding a candlelight vigil. However, symbolic acts and civil disobedience that involve illegal conduct may be outside the realm of constitutional protections and can sometimes lead to arrest and conviction. Therefore, while sitting in a road may be expressing a political opinion, the act of blocking traffic may lead to civil or criminal punishment.
